To all whom it may concern:

Be it known that I, CHEsNEY L. Jonas, a citizen of the United States,and residing at Oakland, in the county of Bergen and State of NewJersey, have invented a certain new and useful Composition of Matter, ofwhich the following is a. specification, such as will enable thoseskilled in the art to which it appertains to make and use the same.

The object of my invention is the production of a composition metalwhich has the appearance of silver and the strength of steel but whichwill not rust by exposure to the atmosphere or to anything else whichordinarily causes metals. to corrode; a further object being to producea metal which will resist most acids and which will take a high polish,can be cast or rolled into bars 01-. sheets, or forged or otherwisefashioned into desired forms, and which is very tough and from whichsprings and like articles may also be formed.

My composition consists of the following ingredients combined in themanner set out.

Nickel 67. 8% Copper; 28. 0% Manganese 02. 5 Iron 01. 5% Vanadium 00. 2%

- taken from the furnace, and the product thus formed is thoroughlystirred and the various component parts mingled.

It is possible, however, to mingle all the component parts, includingthe vanadium,

and then melt the product, but the process of procedure first abovenamed is the one preferred.

The vanadium adds considerable to the strength and toughness of thefinished metal and the amount of vanadium can be varied slightly, butshould preferably never be over 1% of the total mixture, and when theamount of vanadium employed varies from the figures given in theformula, the amount of copper should also be varied to an equal extent.

I may also add carbon to the above ingredients, to the extent of from.18 to 20%, and this will make the metal product harder, the temperdepending on the percentage of carbon employed.

My invention is not limited to the exact proportions of the'variousingredients thereof, as herein set 0ut,-and changes therein andmodifications thereof may be made, within considerable limits, withoutdeparting from the spirit of the invention or sacrificing itsadvantages.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. The composition metal herein described containing nickel, copper,manganese, iron and vanadium.

2. A metallic compound comprising, nickel, copper, manganese, iron,vanadium and carbon, combined.

3. The composition metal herein described consisting of nickel 67.8%,copper 28.0%, manganese 2.5%, iron 1.5% and vanadium 2%, saidingredients being combined substantially as described.

In testimony'that I claim the foregoing as my invention I have signedmyv name in presence of the subscribing witnesses this 7th day ofFebruary 1917.
